Limiting Current Oxygen Sensors with LSM as Dense Diffusion Barrier

Article Preview

Abstract:

A thick film type of limiting current oxygen sensor which uses yttria (8% mol) stabilized zirconia (YSZ) as oxygen ion conducting solid electrolytes and dense La0.8Sr0.2MnO3 (LSM) as diffusion barrier was developed successfully. The oxygen sensor showed excellent performance at oxygen concentrations ranging from 0 to 10 ppm. The advantages of the sensor are simple construction, low cost and potential long term stability.
